The falling film principle requires an even distribution of the feed liquid. To achieve this distrubution one or more distribution trays are located in the top head of the evaporator over the complete tube sheet. Our proven distribution system makes sure that the inner surface of each individual tube is properly wetted. The liquid film moves down the tubes by gravity force. Heat applied through the tube wall effects boiling-off the light fraction from the film. The picture shows a co-current operating evaporator with vapour and liquid leaving the bottom of the evaporator into the separator vessel.

Short path distillation is a thermal separation technology operating at process pressures in the range of 1 to 0,001 mbar. It lowers the boiling temperature and is an excellent method for gentle thermal treatment of heat sensitive, high boiling products. The short path evaporator consist basically of a cylindrical body with a heating jacket, a rotor and an internal condenser. The rotor creates a mechanically agitated, thin product film on the heating surface inside of the body. By means of gravity the product flows down in a spiral path, whereby the volatile portion of the product evaporates. The vapour passes by the shortest route and with practically no pressure drop to the internal condenser. The non-volatile portion reaches the lower part of the evaporator and is discharged through the bottom product outlet. The residual vapours and inert gases flow through the vacuum nozzle to the vacuum system.

AViTEQ-vibrating heat exchanger are used in a number of processes in which bulk solids have to be cooled, heated, dried etc. These special-purpose units are able to perform the heat exchange process during transportation. Usually, this occurs indirectly through the use of double bottoms to accommodate the heat exchange medium (oil, water, air, etc.). AViTEQ heat exchangers are employed in practically every industry (chemical, food, plastics, pharmaceutical, recycling and raw materials). The spiral conveyor, which offers large heat exchange surfaces from a small footprint through its coils, is an especially cost-effective solution. A laser-welded version, which offers maximum density in return for minimum heat admission during manufacturing operations (no welding stresses to cause delays), is playing an increasingly important role for these special units.

For example, For example by pressure reduction in a gas-pressure control. Heat exchangers can also be determined in the reverse mode of operation as coolers. The design is carried out as a steel welded construction in vertical or horizontal design.
